Carrier acquisition technique for mobile radio qpsk demodulator |
摘要 |
A method and apparatus for estimating a frequency of a received carrier wave in a Quadrature Phase Shift Keying (QPSK) system. The invention uses a combination of an FFT, DFT bins, and three point interpolation to estimate a frequency of the carrier wave. The system is robust and compensates for multipath fading and other types of signal degradation. |
